CST_ Screen Media presents a film written and directed by Scott Abramovitch, based on the book “The Locklear Letters” by Michael Kun. No MPAA rating. Running time: 88 minutes. Available Friday on demand. Not that Hale’s Sid Straw is exactly lacking in confidence; it’s just that his confidence is usually misplaced. He’s the kind of guy whose mere presence in the break room at work will have you doing a quick U-turn and hoping he didn’t spot you, the kind of guy who thinks it’s funny to bring a 1980s Major League Baseball star to a wedding as his Plus One just because, the kind of guy who goes on a couple of dates and starts calling his new acquaintance “my girlfriend,” much to her chagrin.
